Hoekopgeloste verstrooiing
Stuur azimutale sweeps waarbij hoekherhaalbaarheid de kwaliteit van de dataset bepaalt.
Specifying this part
What this model has to survive, and what it needs around it
Rotary resolution sits well above the linear axes
Rotary encoders read to around 50 nm equivalent rather than the 2 nm of the linear stages. If angular repeatability drives the measurement, check it against the encoder figure rather than assuming the linear specification carries across.
Vacuum and non-magnetic versions
Most of the range is orderable as .HV (high vacuum), .UHV (ultra-high vacuum) or .NM (non-magnetic). The suffix changes materials, cabling and bake compatibility rather than the mechanics, so specify it against the chamber the stage will live in.
Full series comparison, controller pairing and mounting hardware on the ambient piezo stages overview, or work through the selection with the configurator.
